@ -85,20 +85,22 @@ Some major changes were done to make the mod easier to maintain:
* Improve block textures
* Make a trm for treasurer (separate mod)
* Make variables based on real hardness values (but allow all birthstones to break the same types of blocks, for playability):
#of uses, dig times, and fleshy damage group value now all based on real-life hardness values
(see xlsx spreadsheet for details and sources and extrapolation formulas)
Formulas were determined using Excel:
* #of uses, dig times, and fleshy damage group value now all based on real-life hardness values (see xlsx spreadsheet for details and sources and extrapolation formulas)
* Formulas were determined using Excel:
* Diamond theoretical Brinell explanation: Excel says the curve on 18carat.co.uk, if a power curve, is Brinell = 2.9592*(ans^2.2856) where ans is Moh value
* Other extrapolated Brinell values (rounded to nearest whole number) explanation: Excel says power function for predicting from density is Brinell = 9.0954*(ans^2.9757) where ans is metric density value
* Extrapolated Moh values explanation: Excel says power curve from 18carat.co.uk materials is: Moh = 0.6514*(ans^0.4269) where ans is Brinell value
(to use Speedcrunch to get values not listed, enter the number without any equation, then paste the formulas above exactly to use that "answer" as a variable--see spreadsheet's "Hardness - Extrapolated" sheet for spreadsheet version of formulas)
